Breaking with the traditional numbering sequence, the camera is marketed simply as Leica M.
An accessory electronic viewfinder turns the camera into an SLR and an R lens adapter is also available, allowing the majority of R lenses to be used and providing, after many years, a full frame Leica digital camera capable of using R lenses.
The camera's firmware includes profiles of many M and R lenses to optimise reproduction. M lenses fitted with the latest identifying code will automatically select the correct profile, for others this must be manually selected.
